Specification of Letters Patent.

Application filed February 10, me. Serial No. 817,880.

To all whom it mag concern? Be it known that I, ARTHUR B. FRENZEL,

a citizen of the United States, residing at Denver, in the county ofDenver and State of Colorado, have invented certain new and useful Improvements in Water-Lifting Apparatus, of which the following is a specifi- I cation.

My invention relates to impro ve'nrents in water lifting apparatus and its ob ect resides in-the provision of an apparatus which is capable of lifting water by the action of a rotary, helical element from a shallow depth in river-bottoms and the Iike,v-'ith the minimum of power in relation to its capacity.

In accordance with my invention I prowide a cylindrical, open-ended barrel connected at its upper end to a conduit of inverted truncated cone form, with which it,

is in axial alinement. The barrel is surrounded by a foraminous casing for the purpose of excluding stones, sand and other solids from its open, lower end, and the entire device thus constructed is adapted to be inserted into an excavation formed in a river bottom or other place having a subterranean water supply. The conduit and the therewith connected barrel are suspended from a structure which in practicerests upon the surface of the ground and which supports the operative parts of the apparatus. These parts include a hollow shaft which is rotatably mounted in the axis of.

thedevice, upon a step at the lower. end of the casing which surrounds the pump-barrel, and in a bearing which is formed in a yoke which is mounted on the supporting structure.

The means for imparting a rotary movement to the shaft include a driven wheel which is secured at the upperend thereof and by means of which it is suspended from the support which to this end, is provided with a bearing, preferably of the anti-friction, cone roller type.

Mounted on the shaft within the barrel is ahelical lifting element of gradually increasing pitch which may be formed either of a plurality of screw propellers or of a single or multiple advancing spiral blade. ..,;;Means are provided .for counteracting the swirling .motion imparted to the upwardly impelled column 'of water and a collar on the shaft ,prevents its upward displacement by engagement with the supportmg structure.

In" the operation of the apparatus, the

vation of the river-bottom, which is made of suiiiclent diameter to-permit of surrounding the same with a wall of broken stone or rocks to prevent clogging of the foraminations in the casing which surrounds the pump-barrel.

If so desired the'excavation may be lined by inserting thereinto a perforated cylinder which can be secured to the supporting structure, in which case the rocks are placed in the space between said casing and the alinedconduit and barrel with which it is concentric.

The water which enters the pump barrel;

practically free from solids, is raised by the rotary motion of the helical element, which is imparted thereto by power applied to the driven wheel at the upper end of the shaft.

The gradually increasing pitch of the lifting element gives to the ascending column of liquid, an upward thrust'which greatly increases the lifting power of the apparatus. The gradually increasing diameter of the conduit in which the water rises to a dis- Patented May 23,1916.

barrel and conduit are inserted in an exca charge spout at the upper end thereof, de-

creases the speed of the water as it rises "after leaving the pump-barrel, and thereby renders the movement of the operating parts more effective, and the means provided for counteracting the swirling motion imparted to the water by the action of the lifting element, further aidv 1n imparting avsteady.

flow to the rising column and in eliminat- 'ing forces retardative to the upward motionof the same.

Thesuspended mounting of the operative parts of the pump, permits of their being removed for cleaning or repairs without the necessity of disturbing the stationary parts of the apparatus, and without the use of special tools'or the employment of skilled driving shaft 14 which by means of a pulley 17 which are mounted on the portion oftheinoperative by freezing, the introduction of steam into the shaft will be effective to restore it to its working condition.

Having thus described the construction, operation'and advantages of my improved water lifting apparatus, I will now proceed to describe the parts of which itis composed, in detail, by reference to the accompanying drawings in the varlous views of which like partsjare similarly designated,

, and in which,

Figure l, is a. vertical, axial 1 section through the apparatus in its preferred form, Fig. 2, a similar section showing a modification in the construction of the same, Fig. 3, a longitudinal section through the barrel of the apparatus, showing a modified construction of the helical lifting element, rotatably disposed therein, Fig. 4, a section taken along the line 4-4, Fig. 1, and Fig, 5, a transverse section along the line 55, Fig.2.

The. reference numeral2 designates 'the barrel surrounded by the foraminous'casing 3 which at its lower end is closed by a perforated bottom 4.

The conduit 5 which as hereinbefore explained, is made'in the form of an inverted, truncated cone, has at its lower end, a flange Y by which it is attached to flanges formed at the upper ends of the casing and the barrel,

for the urpose of their connection and of clrging the space between them at their said en s.

The numeral 6 designates the supporting structure which may be of any suitable construction and upon which is mounted the yoke 7 provided with the cone-roller, antifriction bearing 8..

The tubular shaft 9 'rotatably disposed in theaxis of the axially alined conduit and barrel is supported upon a ball-bearing step 10 in the center of the bottom of the casing 3, and the bevel gear-wheel 12 secured at the upper end of the shaft is rotatably supported in the bearing on the-yoke.

The gear wheel is in operative engagement with a inion 13 mounted at the end of a 15 may be connected with any convenient driving medium.

A collar 16 which is detachably secured to the shaft beneath the yoke, serves to prevent its upward displacement and a screw thread formed internally at the upper end of the shaft as best shown in Fig. 2, may be used for the connection of a tubular conduit through which a fluid is introduced into the shaft for the purposes hereinbefore set forth.

The helical lifting element of my invention consists in its preferred form, as shown in Fig. 1, of a plurality of screw propellers shaft within the barrel in alternate order with devices for counteracting theswirling motionthey impart to the rising column of in the water. These devices consist preferably of .rings 18 having radial arms 19 which upon their sides forward'with relation tothe direction of rotation of the element, have baffles 20 provided by vertically extending ribs.

The devlces are supported in the barrel upon lugs 21 secured upon its mner surface to receive the ends of their radiating arms While the rings are placed concentrically around the shaft.

plained, made of different pitch which increases progressively from the lowermost screw to that nearest the upper end of the barrel.

In the form shown in Fig. 3, the screw propellers are mounted one upon the other without'baflling devices of the construction shown in Fig. 1, and in Fig.- 2 the lifting element is provided by a double helical blade 22 of. gradually increasing pitch which is mounted on the shaft, inside the barrel, by means of a sleeve 23 around which it is formed..

The conduit through which the water lifted by the action of the helical element, rises to the surface of theground, is preferably'made of longitudinally corrugated metal, the corrugations serving to stop any swirling movement in the column of water after it has left the barrel, as well as to strengthen the construction.

The apparatus is as shown in Figs. 1 and 2, placed, in practice, in an excavation 24 and surrounded by broken stones or rocks 25.

In the construction. shown in Fig. 1, the excavation is lined by means of a perforated casing 26 connected with the supporting structure by means of a flange, to aid in excluding solids from theoperating parts of the apparatus, and in both Figs. 1 and 2 the level of the water in the subterranean source is-indicated by a line designated by the numeral 27.

Having thus described my invention what I claim and desire to secure by Letters-Patenfla is 'f pump-comprising an upright, 0 enended barrel, a conduit connected at the upper end thereof, and a lifting element comprising a plurality of screw-propellers which mcrease in pitch progressionally from the lower one to the upper one, mounted in the barrel for rotation about a common, vertical axls.
